Short range guided wave testing (SRGWT) is an application of guided ultrasonic sound waves using special types of probes. When the guided waves hit the discontinuities, the mode converted sound is reflected back and received by the transducer.

Nowhere is the need for material integrity more obvious than in medical devices that are implanted into human beings. A failed device inside an aircraft or power plant may, under some circumstances, cause a problem.

Ductile iron is an iron-carbon casting material whose matrix includes carbon in the form of nodular graphite particles. Rounded graphite nodules in the ductile iron matrix offer greater resistance to stress concentration when compared to graphite flakes (as in gray cast iron) and, therefore, inhibit the creation of cracks.

Eddy current testing uses the principle of electromagnetic induction to detect flaws in conductive materials.

An important element in ensuring the quality of finished parts is nondestructive testing (NDT). NDT is the inspection of material or parts without impairing their future usefulness.
